I am on federal Supervised release. I have had several positive skin test results from the farm cam skin patch company all of my urine tests which were surprised random urine test have come up negative.

Wondering about supplement
Date: 8/5/2013
I have been taking prilosec on and off for the last 2 year or so, then i stopped for 3-4 weeks or so. However i took maybe one or 2 pills 2 weeks ago. My question is i have a urine test on august the 13 and i like to know if it still will show in my urine test. I am taking AXIA3 that i buy from the whole food market to release my hard burn, those axis3 will those reflect in my urine test? i also took some homeopathy tables, those tables are for Brochitis & Asthma aide/boericke. MY question is those homeopathy tables show as a positive in a urine government test. I hope u can response as fast as possible so that i know what to do. Thank you for your help.

Rifampin
Date: 8/5/2013
My local District Attorney does not believe that my drug test was a false positive! I am currently taking Rifampin and got a positive for opiates! On your website my rx is listed. Both the pharmacy and district attorney say its impossible that this medicine can contain opiates! Please help me.

Shannon
AskDocWeb: No one here said anything about Rifampin containing opiates – it does not. Rifampin is listed because several sources say that urine tests may show a false positive for opiates (References: 25 and 32 and 57). Check those references and let you District Attorney argue with the American Medical Association.

Numbing medication?
Date: 8/5/2013
Hello, I recently went to the dentist and they extracted a tooth. Later that day I was in the emergency room for another reason. They took blood and urine from me. My lab results showed a positive for meth. I do not do meth. After much shock, the only explanation could be that it was from the the numbing medication that the dentist had injected into my gums earlier for the extraction. Could it be that it caused the false positive on my lab work?

Rebecca
AskDocWeb: It highly doubtful but you may want to get a GC/MS confirmation test to rule out that possibility.

Any chance of a false positive?
Date: 8/6/2013
I took a pre-employment drug screen on Friday afternoon. That morning I took 2 Iburpofen (200 MG each). I am also currently taking Doxycycline Hyclate (2 50MG tablets daily). Is there any chance either of these could cause a false positive? I took the test at Quest Diagnostics.

Marc
AskDocWeb: When taking a urine test for drugs of abuse there is always a chance of a false positive. That is why a additional testing by a more accurate test is recommended.
